Nuclear proliferation is the spread of nuclear weapons, fissionable material, and weapons-applicable nuclear technology and information to nations not recognized as Nuclear Weapon States by the Treaty on the Non-Proliferation of Nuclear Weapons, also known as the Nuclear Non-Proliferation Treaty or NPT.
There are two main types of nuclear reactions, fission and fusion. Nuclear fission is when the nucleus of a large atom is split into two or more fragments. This releases neutrons and energy. Nuclear fission can occur spontaneously, or it can be started when nuclei are hit by particles.
